Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87378, here are decompositions:

19 + 87359 = 87378
41 + 87337 = 87378
61 + 87317 = 87378
79 + 87299 = 87378
97 + 87281 = 87378
101 + 87277 = 87378
127 + 87251 = 87378
157 + 87221 = 87378

Showing the first eight; more decompositions exist.
